Notes: Blank-backed, no company name listed. This is an anonymous set
with numbering. The first 200 numbered cards are there, then the next number is
256. The numbers from 256 to 300 are only the last 5 in each group of 10, such as
266-270. The first five numbers in each series of 10 were not issued, such as
numbers 261-265.

I gave it the name "Dutch Numbered Set 3" to distinguish it from other
similar anonymous sets - the cards do not say Set 3 on them.

Date info: Natalie Trundy was in only 1 episode of Bonanza, which aired in 1960. I originally guessed a date of 1961 for this set, and that is confirmed by an original packet that was used to issue these cards, which is titled "Film o TV-61".
